C++ help: quick question... how do I specify which base a number is?

[Jumpem]

0x* will specify hex.

Is there a way to specify a number as binary, and as decimal/long?

You mean prepend a number so when you read it, you know what base it's in?

If I see 0x123 - its hex
If I see 01010 - I'm *assuming* its binary
If I see 12351 - I"m *assuming* its base10

I don't think other than the 0x nomenclature for Hex, that there are standardized ways to represent the other Bases, other than using the base as a subscript after the actual number like textbooks do.

Why do you have to store it in a base? Why not just convert it when you're going to display it?

See here for examples of what I mean: http://www.swarthmore.edu/NatSci/echeeve1/Ref/BinaryMath/NumSys.html#posint

Not sure how you are going to generate subscripts using basic I/O.

do you mean specify the base for a reader to read? or for the compiler?

I have to do a bunch of masking of addresses and opcodes. I'm converting everything to decimal for input now, but it'd be clearer in some cases if I could use binary. But if I use "1010111" the compiler will think it's decimal.

you would have to represent it as a hex and mask it from there, for example, if you want to represent binary 1111 you'd do

0x0000F

I think 0xFF is hex, 1011010b is binary, and regular #s are decimals.
